[recommendation request] Would love your opinion on vintage watches

Good day everyone,

I was looking into buying a nice(r) watch for the first time now that I'm out of grad school (to this point I've only worn old, probably cheap Seikos). I would love some recommendations on vintage watches that can be bought used online for sub $5/600. I don't necessarily love a giant dial, certainly like gold tones, and would like to go for analog.

Any recommendations would be highly appreciated. Thank you all.
